' BENCH-VISE.

Specification of Letters Patent.

Application filed Jul 23,1917. Serial No. 182,146. 1

T 0 all whom it may concern:

Be it known that I, JOHN R. LONG, citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new andusefuliIm- 'provements in Bench-Vises, of which the following is a specification. This is an improvement in bench vises', substantially as shown and described and particularly pointed out in the claims.

Figure l is a sectional elevation of the vise, taken on a line corresponding substantially to w, m Fig. 2. Fig. 2 is a cross-section on a line corresponding to 22, Fig. 1. Fig. 3 is aplan View with the jaws placed horitherein as in Fig. 1, and as hereinafter fully described. Fig. 4 is a front end elevation of Fig. 3. Fig. 5 is a sectional detail on line 5, 5, Fig. 1, showing the square shank of the tubular nut for the operating screw. Fig. 6 is a detail of the said nut and Fig. 7 is a detail of the tightening collar.

In the present construction the jaws may be set to any desired angle in eitherv vertical or horizontal relations without the necessity of changing the position of the vise on the post or support. and the present improvement also provides for a powerful grip. on the post when the jaws are clamped, and which eliminates considerable past difficulty in these particulars. 1

The provision herein herein for rotating the jaws to all degrees in either plane is especially emphasized, and difierentiates the construction from anything shown in the foregoing patents or that is known to me in other Vises. The present construction also insures absolutely parallel jaw-faces, and remedies defects in my Patents Nos. 667,151 and 1,196,560, particularly the tendency in the outer j awto grip tighter at the topthan at the bottom; This objection is impossible in-the. present vise, as hereinafter more fully set forth.

These comparisons serve in a measure to show the mechanical and operating differences and advantages herein over the prior patents, notwithstanding that certain of the parts here and there bear structural resemblances tolike parts in the said patents. .Thus, the base I) is adapted to be removably bolted or screwed to a suitable support and is provided with a preferably hollow cylindrical post 2 of suitable elevation substantially as in Patent 1,196,560. But the unitary yokey, herein is provided with two bores, 3 and 4, at right angles to each other and adapted to engage rotarily and fit snugly over orupon the post 2 of the base according as to whether a vertical or horizontal position of the jaws be wanted, Figs.

1 and 3, and in addition to this-there is what' may be termed a. longitudinal bore or opening in and through which the jaw extensions or shanks are mounted. Also, it will be noticed that the yoke y is split or slotted at s 6 through thewalls ofboth bores in such a manner that the said bores shall be compressible or contractible in sufiicient measure to clamp the same firmly upon the post 2 when definite locking'of the jaws'in any adjusted position is desirable. for a given work. This of course contemplates rotation of the jaws in the yoke to get the 'desired'angle and then looking the jaws in such position by the means provided for this purpose.

The said means involve the two jaw membersJ and J each of which has a tubular shank or extension 8 and 9 respectively, projected into'the coaxial openings through the front and rear wingsof the yoke relatively above the said bores, the shank 8 of the inner jaw J having its bearingsimmediately within the said openings, while the shank 9 hasits bearings within the hollow shank of the said inner jaw and terminates just within the flanged or partiallyclosed end 10 thereof.

The shank or stem 8 of the inner jaw is cylindrical. and tubular and adapted to be rotated in its bearings in the yoke, and has an internal rectangular bearing 12 adapted to receive the correspondingly shaped shankv or extension 9 of the outer jaw. The said aw 9 is therefore slidable lengthwise in'the said bearing but not rotatable independently of the inner jaw.i This serves to keep the twoj aw faces in opposite working relations at all times at whatever angle they may occupy in the yoke. In addition to the angular close-fitting bearing 12 the inner jaw also provides a support 13 at its front for the outer jaw, and altogether the said jaws are so related and mutually supported that positively parallel jaw-faces. arev maintained at all times however near or far apart they may be in engaging the work. is laid on this feature because it lies at the bottom of the present invention.

Now, as further material details, it will be observed that the operating screws 8 Patented May 7,1918.

Emphasis engages in a tubular nut 92,, which has an annular head or flange 15 hearing outwardly against the otherwise closed or flanged end 10 of inner jaw shank S, and that said nut has a square shank 16 immediately outside said flange engaged through a correspondingly square or angular hole through said otherwise closed end 10. The outer end of nut 12 is screw threaded to receive a nut 18 thereon, and a disk shaped collar 0, Fig. 7, has. a, square hole through its center engaged upon the said, shank 1.6 and seated about its inner. recessed edge against the edgeof the yoke. v i It willbe noticed that a definitev but. limited space is provided for between said collar and the endlO of the inner jaw, which stops short of; the outer edge portion of the yoke,engaged by saidcollar, and the jaw J has an annular shoulder 14 which engages against the edge of the forward portion or wing of the yoke. It follows, of course,when the nut 18 is tightened, that a pull will be exerted by the flange 15 on inner jaw shank Stand correspondinginward pressure against the yoke by collar 0, and having the yoke slotted at 6-through the walls of the bores 3 ands, thereof, it follows thatthere must be .a clamping effect exerted onthe front and rear wingsofthe yoke toward each other andwhicli will close the bore that may be in use at the time tightly upon post 2 and lock theivise against rotation thereon. Otherwise, or wl1en nut18 isloosened, the vise may be rotated orturned to any preferred angle,'but -the clamping of thejaws is independent of this operation and through screw .9. Notice. that the yoke is provided with an opening between its wings, on front and rear, down to the said slot 6.

i A bushingQO fixed in the outer jaw serves as a bearing for the operating screw, and a collarf2l pinnedon the screwxbearsagainst saidbushingand confines the screw in working relations in said jaw. Thehead 22- of sald screw which carries the handle rod It bears directly against the outside ofthe jaw. From the foregoing description and as compared especially with my Patent No. 1,218,? 88, it will be seen that the invention herein resides primarily in theunitary or one piece yoke as compared with the sectional ortwo piece yoke-inthe said patent, and. the netiresult is to get uniform and exact gripping over the entire surface and depth' of the jaws, whereas in Patent 1,196,560 the outer jaw tends to always grip the work tighter at the top than lower down in the jaws and which is a serious defect which has been overcome in the present construction.

Ihe opening or ecess 6 transversely down into the yoke of course is necessary to obtain the clamping effect upon post 2 when the ends or win s w and 'w on either side of said recess are drawn toward each other. The said yoke is of cast metal, but with the central recess between the wings and the opening by slot 6 into the bores 3 and 1, there is sufficient spring in the remaining metal about the outer walls of said bores toeffect clamping upon post- 2. Of course in any case the said bores 3 and 4 fit quite snugly upon the post so that a comparatively slight compression will make .the clamping secure, and hence, also, there is no unfavorable, effect transmitted to the aws. 1
